His companion - Perhaps one of those mentioned in Judges 14:11. The transaction denotes loose notions of the sanctity of marriage among the Philistines. It should be noted carefully that the practical lesson against ungodly marriages comes out most strongly in this case and that the providential purpose which out of this evil brought discomfiture to the Philistines, has nothing to do with the right or wrong of Samson's conduct.

But Samson's wife was given to his companion - This was the same kind of person who is called the friend of the bridegroom, John 3:29. And it is very likely that she loved this person better than she loved her husband, and went to him as soon as Samson had gone to his father's house at Zorah. She might, however, have thought herself abandoned by him, and therefore took another; this appears to have been the persuasion of her father, Judges 15:2. But her betraying his secret and his interests to his enemies was a full proof he was not very dear to her; though, to persuade him to the contrary, she shed many crocodile tears; see Judges 14:16. He could not keep his own secret, and he was fool enough to suppose that another would be more faithful to him than he was to himself. Multitudes complain of the treachery of friends betraying their secrets, etc., never considering that they themselves have been their first betrayers, in confiding to others what they pretend to wish should be a secret to the whole world! If a man never let his secret out of his own bosom, it is impossible that he should ever be betrayed.

But Samson's wife was given to his companion,.... By her father, and with her consent, both being affronted and provoked by Samson leaving her, who judged her not only to be injured, but hereby discharged from him, and free to marry another:
and whom he had used as his friend; though there were thirty of them that were his companions, yet there was one of them that was the principal of them, and was the most intimate with him, whom he used in the most friendly manner, and admitted to a more free conversation than the rest, the same that is called the friend of the bridegroom, John 3:29 while the others were called the children of the bridechamber, Matthew 9:15. It is not unlikely that this person had too much intimacy with Samson's wife before, and so had the secret of the riddle from her, and so very readily married her, as soon as Samson departed; and all this furnished out an occasion and opportunity, which Samson sought for, to be revenged on the Philistines, as in the following chapter.

Samson's wife was given to his companion, whom he had used as his friend--that is, "the friend of the bridegroom," who was the medium of communicating during the festivities between him and his bride. The acceptance of her hand, therefore, was an act of base treachery, that could not fail to provoke the just resentment of Samson.

"And Samson's wife was given to his friend, whom he had chosen as a friend." מרע is not doubt to be understood here in the sense of "the friend of the bridegroom" (John 3:29), ὁ νυμφαγωγός (lxx), the conductor of the bride-namely, one of the thirty companions (Judges 14:10), whom Samson had entrusted with this office at the marriage festival. The faithlessness of the Philistines towards the Israelites was no doubt apparent here; for even if Samson went home enraged at the treacherous behaviour of his wife, without taking her with him, he did not intend to break the marriage tie, as Judges 15:1-2 clearly shows. So that instead of looking at the wrong by which Samson felt himself aggrieved, and trying to mitigate his wrath, the parents of the woman made the breach irreparable by giving their daughter as a wife to his companion.

Was given - By her father. Whom he had used - That is, to the chief of the bride - men, to whom he had shewed most respect and kindness.
